How EGL Compares To Other Diamond Laboratories

While there were once only one or two laboratories that could be used for the evaluation of diamonds, quite a lot of institutes have risen in the past few years, making it quite difficult for consumers to know which laboratories they should trust and which ones they should avoid. In this post, we would like to focus on one particular laboratory that has gained a mixed reputation – for being both good and bad. The problem, however, is that it seems like this institute has rather become popular amongst the more scaly suppliers of diamonds – since they are the ones that can greatly benefit from the way the EGL, also known as the European Gemological Laboratory, grades a diamond. The consumer, on the other hand, eventually leads a loss when they have purchased a diamond appraised by this institute, which can be quite disappointing once they determine they had paid too much for the loose diamond side stones. Let’s take a closer look at the EGL and how this institute compares to the GIA (Gemological Institute of America) and the AGS (American Gem Society).

What You Need To Know About The European Gemological Laboratory


The very first negative fact that you will come across when you try to determine the reputation of this institute and, of course, try to obtain more information about the European Gemological Laboratory, is that there does not seem to be an official website for the EGL. Instead, there are numerous websites that represent local divisions of this institute. We did find one particular website, named “E.G.L. Platinum” that seems to represent this institute in some ways. On this website, we found some basic information about the EGL, but we could not find any links to a certificate validation service – this is a tool that is essential for the consumer and is offered by almost all other institutes that offers diamond appraisal services. We were able to identify some potentially useful information on this website, however, such as an “EGL College” section that offers education and also courses on the grading process of diamonds. Unfortunately, due to the numerous complaints about the inaccuracy of the EGL’s diamond grading process, we do not know what quality and standards the courses of this college is.

Tips For Buying A Diamond Certified By The EGL

GIA Certified-diamondIf you do come across a diamond multi stone rings that you would like to purchase, but find that it comes with an EGL certification, then do not fear. There is still a way in which you can buy such a diamond and avoid being ripped off too much. The best solution for such a problem would be to have the diamond appraised by another institute. Try to get the diamond appraised by a company such as the GIA or the AGS. If the grading report that comes back defers a lot from the one that was originally provided to you (the EGL diamond certificate), then you can present the new certificate to the jeweler and see if you can negotiate a better price for the diamond. In some cases, the jeweler may negotiate – but, do not get your hopes up too high as some jewelers may purposely use EGL to increase the prices of their diamonds.


While the European Gemological Laboratory is quite popular amongst many jewelers, it seems like the institute is not as popular amongst consumers. Many reports claim that the EGL is relatively “loose” when it comes to appraising diamonds and, in the end, this can cause a jeweler to overprice a diamond that has been graded by this institute. We highly recommend opting for diamonds that have been graded by more reputable diamond grading institutes, such as the AGS and the GIA.
